Environment-friendly water-based printing ink preparation process

Abstract

The invention belongs to the field of ink preparation, and particularly relates to an environment-friendly water-based printing ink preparation process which comprises the following steps: S1, conveying raw materials: intermittently and equivalently conveying various different raw materials at the same time by using a conveying mechanism, and containing the raw materials by using a mixing box; s2, heating and mixing: in the step S1, a conveying mechanism can drive an efficient mixing mechanism in a mixing box while working, so that various different raw materials in the mixing box can be heated, mixed and prepared; and s3,performing waste gas treatment: in the step S2, a filtering mechanism in a mixing box can be driven while an efficient mixing mechanism works, so that toxic gas generated in the mixing box can be automatically purified. The problem that an existing water-based printing ink preparation device cannot conveniently and stably purify waste gas in the working process is solved; therefore, the environment-friendly water-based printing ink preparation process needs to be provided to meet the requirements of users.

Description

technical field [0001] The invention relates to the field of ink preparation, in particular to an environment-friendly water-based printing ink preparation process. Background technique [0002] Water-based printing ink is mainly prepared by mixing water-soluble resins, organic pigments, solvents and related additives. It is an important material for printing. Various printings such as packaging and decoration, architectural decoration and electronic circuit boards, and with the increase of social demand, the types and output of inks have also expanded and increased accordingly. Therefore, it is necessary to use the preparation process and preparation equipment to prepare and produce water-based printing inks. [0003] For example the publication number is CN113134423A a kind of water-based printing ink preparation method, "it has used a kind of water-based printing ink preparation device, and this water-based printing ink preparation device comprises preparation box, grindi...

[0003] For example the publication number is CN113134423A a kind of water-based printing ink preparation method, "it has used a kind of water-based printing ink preparation device, and this water-based printing ink preparation device comprises preparation box, grinding mechanism, screening mechanism, scraping material mechanism and collection box, The preparation box is a rectangular structure, and the inner wall of the preparation box is provided with a grinding mechanism, a screening mechanism and a collection box in sequence from top to bottom, ..., S2, screening treatment: when the ink after grinding is passed through the screening mechanism Raw materials are screened; S3, falling material collection: the ink materials that fall after sieving are collected through the collection box, and made into water-based printing inks. Since water-based printing inks need to use a variety of raw materials in the preparation process, and the water-based Although the printing ink preparation method and preparation device can uniformly grind the raw materials, they cannot quickly and stably mix various raw materials uniformly during the working process, and thus cannot ensure the stability and high efficiency of the subsequent preparation of water-based printing inks. ; Because traditional solvent-based inks contain a large amount of organic solvents, a large amount of toxic waste gas will be emitted during production and construction, which will directly endanger human health and cause environmental pollution. Therefore, it is necessary to provide an environmentally friendly water-based printing ink preparation process to meet the needs of users
